## What is FieldPad?

FieldPad is the only app purpose-built for HVAC and refrigeration technicians. Track refrigerant inventory, calculate leak rates, manage EPA compliance records, and invoice customers — all from your phone, even without cell service.

Whether you're a solo tech or running a small crew, FieldPad replaces paper logs, spreadsheets, and generic invoicing apps with a single tool designed for how you actually work.

EPA 608 & AIM Act Compliance
Log refrigerant recovery, recharge, and leak test data. FieldPad calculates leak rates using EPA Section 608 and AIM Act (Subpart C) formulas and compares results against regulatory thresholds for commercial refrigeration, comfort cooling, industrial process, and transport systems. Track repair deadlines, verification tests, chronic leaker reports, equipment inspection schedules, and refrigerant disposition records. A2L safety checklists help you document mandatory safety steps when servicing next-generation refrigerants. Export audit-ready compliance reports when you need them.

Invoicing & Signatures
Create professional invoices and estimates from completed jobs. Add line items, apply tax rates, collect digital signatures on-site, and share PDF invoices by email,  all before you leave the job site. Line item templates for common HVAC services save time on every invoice.

Refrigerant Cylinder Tracking
Scan cylinder labels with your camera to capture refrigerant type, serial number, and weight — no typing required. Track inventory levels, log usage per job, and get low-stock alerts on your dashboard.

Built for the Field
FieldPad works fully offline. Create jobs, log compliance data, generate invoices, and scan cylinders with no internet connection. Data syncs automatically via iCloud when connectivity returns. Glove Mode enlarges all touch targets so you can tap accurately with work gloves on. Three display themes, including Sun Mode, keep the screen readable in any lighting.

Job & Client Management
Schedule and track service calls. Manage your client directory with address autocomplete. Set up recurring maintenance jobs. Detect scheduling conflicts before they happen. View today's jobs, pending invoices, and compliance alerts from your dashboard.

Get Started Free
FieldPad's core features are free to use with generous limits — up to 10 jobs, 5 clients, 10 invoices, 20 compliance logs, and more. Upgrade to FieldPad Pro to remove all limits and unlock recurring jobs, data export, business logo on invoices, and unlimited OCR scanning.

FieldPad Pro Subscription
FieldPad Pro is available as an auto-renewing subscription. Payment will be charged to your Apple ID account at confirmation of purchase. Your subscription automatically renews unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscription in your Apple ID account settings (Settings > Apple ID > Subscriptions). Any unused portion of a free trial period, if offered, will be forfeited when you purchase a subscription.
